To prevent a driver from feeling an annoyance of an alarm and steering of a steering wheel when the driver makes a vehicle deviate from a lane on the basis of his/her own intention.SOLUTION: When a risk of deviation of a vehicle from a lane is determined, a lane deviation prevention device prevents the deviation by issuing an alarm by using an alarm device, and by steering a steering wheel. An electronic control device determines that the vehicle is skewed with respect to the lane on the basis of a position of the vehicle which is detected by a CCD camera (S320), starts to prohibit an issuance of the alarm, and also starts to prohibit the steering of the steering wheel (S350) when it is determined that steering torque Ts detected by a steering torque sensor is equal to or higher than reference steering torque (S330), and when it is determined that the skew of the vehicle with respect to the lane is finished in a situation that the issuance of the alarm and the steering of the steering wheel are prohibited (S360), releases the prohibition of the issuance of the alarm and the prohibition of the steering of the steering wheel (S370).SELECTED DRAWING: Figure 3

    【課題】運転者が自らの意思に基づいて車両を車線から逸脱させる場合に、運転者が警報及び転舵輪の転舵の煩わしさを感じることを防止する。【解決手段】車両が車線から逸脱する虞を判定したときには、警報装置による警報を発出し転舵輪を転舵して逸脱を防止する車線逸脱防止装置。電子制御装置は、CCDカメラにより検出された車両の位置に基づいて車両が車線に対し斜行していると判定し(S320)、且つ操舵トルクセンサにより検出された操舵トルクTsが基準操舵トルクTsc以上であると判定したときには(S330)、警報の発出の禁止及び転舵輪の転舵の禁止を開始し(S350)、警報の発出及び転舵輪の転舵を禁止している状況において、車線に対する車両の斜行が終了したと判定したときには(S360)、警報の発出の禁止及び転舵輪の転舵の禁止を解除する(S370)。【選択図】図3
